MOTOR.

SPECIFICATION forming part of Letters Patent No. 509,043, dated November21, 1893..

Application filed February 13, 1892. Serial No. 422,055. (No model.)

I To all whom; it may concern:

terns; and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart' to which it. appertains to makeand use the same, reference beingbad to the accompanying drawing, and to the letters of reference markedthereon, which form a part of this specification. Y

This invention relates to regulators or g'overnors for controlling thespeed of motors designed for operating small machinery and which areprincipally run by spring power as a convenient means for developingforce.

The improvement consists of a shaft having a spiral portion and providedwith pivoted weighted arms which are the vital controlling means forregulating the speed, and a sprocket wheel on a shaft which isoperatively connected with the train of gearing, and which a'ctuates acounterbalanced lever used to transmit motion to the mechanism to beoperated as will'be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a side eleva-- tion of a motor embodyingour invention showing its application to a pump. Fig.2 is an end viewofthe mechanism. Fig.3 is a detail View of the sprocket wheel and theshaft having the spiral portion in mesh with the said sprocket wheel.

The frame T for supporting the operating parts of the motor is ofordinary construction best adapted for the purpose. The shaft S isprovided near one end with a gear wheel D, and supports a spring barrelPof well known construction and arrangement to set the train. of gearingin motion. A ratchet wheel E secured on the shaft S is engaged by a pawlF which is pivoted to the barrel P to hold the spring when wound as willbe readily understood. A second shaft S parallel with the shaft Sand journaled above the latter is supplied near one end with a-pinion G whichmeshes with the gear'wheel D, and near the other end'with a gear wheel Bwhich'rneshes with a pinion h on a shaft' S also parallel with theshafts S and S. This shaft S has a sprocket wheel I at one end and adisk K arms will stand at right angles to the shaft A as shown inFig. 1. Hence, these weighted arms will fly out more or less accordingto the speed at which the said shaftA is driven. Obviously, thegreaterlthe angle at which the weighted arms stand to the shaft A, thegreater the force required to rotate the said shaft A. Should the motormeet with a slight obstruction the momentum of the said weighted armswill be sufficient to carry the motor or driving force over or past thesaid obstruction like a fly wheel.

The disk K has a wrist pin C which is adapted to travel in a slot 0 in acounterbalanced lever 'N. The weight J movable on the to counterbalancethe load imposed on the opposite end of the said lever so that the motorhas nothing to do but perform actual work. It will be observed that thegreater the an gle in which the weighted arms-stand from the shaft A,the greater theleverage obtained for the resistance of the air; hencemore force will be required to rotate the shaft A when the arms stand atright angles thereto than if the said arms occupied a position betweenthe horizontal and the perpendicular. Hence, if the parts are sodisposed that the weighted arms stand at right angles to the shaft Awhen the motor is not loaded, the speed will be proportionatelydiminished according to the amount of work imposed on the motor as willbe readily understood.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. In a motor the combination with the train of gearing comprising shaftS having wrist pin 0 and sprocket wheel I, of a controlling mechanism tocarry the motor over a-slight said spiral shaft to control the speed ofthe I motor and act in the capacity of a fly wheel, and a powertransmitting lever having a slot toreceive the said wrist pin, andhaving a weight adjustable thereon to balancethe load and connectionscarried by the said lever, 15 substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
